les sessions sous cocoon
Bonjour, est ce que quelqu'un pourrait bien m'expliquer un peu le principe de fonctionnement des sessions sous cocoon? J'ai lu les session contexts du site mais j'ai pas bien compris. Merci d'avance. _ MSN Hotmail : créez votre adresse e-mail gratuite à vie ! http://www.imagine-msn.com/hotmail/default.aspx?locale=fr-fr - Liste francophone Apache Cocoon -- http://cocoon.apache.org/fr/ Pour vous desinscrire : mailto:[EMAIL PROTECTED] Autres commandes : mailto:[EMAIL PROTECTED]

I need to be more careful. Obviously, the above email was
not meant for
the mailing list. But now my mistake has been made:
I had the following pipeline:
map:match pattern=images/*/**/*
map:read src=/data/content/tsg/cmsblocks/holidayImg/{2}/{3}
mime-type=image/jpeg type=image-op-resize
map:parameter name=size-width value={1}/
map:parameter name=size-preserve-ratio value=true/
/map:read
/map:match
Now, this does not preserve ratio, but this does:
map:match pattern=images/*/**/*
map:read src=/data/content/tsg/cmsblocks/holidayImg/{2}/{3}
mime-type=image/jpeg type=image-op-resize
map:parameter name=size-width value={1}/
map:parameter name=size-height value=1/
map:parameter name=size-preserve-ratio value=true/
/map:read
/map:match
I have had a look for the ResizeOperation, and it looks like
it doesn't
need a height. Am I missing something?
I once used this to resize jpegs (and it worked):
The reader:
map:reader logger=sitemap.reader.ImageReader name=imageresource
pool-max=32
src=org.apache.cocoon.reading.ImageReader/
The pipeline:
map:match pattern=/binaries/**.jpg !-- so it won't match .gif or
.png etc --
map:read type=image
mime-type=image/jpg
src=/my-path-to-binaries/{1}.jpg
map:parameter name=width value=50%/
/map:read
/map:match
You use size-width as parameter, I used width. Maybe that's the difference? Or
are you using an other reader?

Re: Apologies
As of 2.1.9 there is a new reader called imageop. Check out the
samples for it. I am using that. Imageop is causing me problems. If I
cannot get it to work, I may try your way.
Cheers.
Kamal.

RE: Catching a NullPointerException to display custom error page
Yes Reijn I am using the ExceptionSelector already for catching page not found and invalid continuation exceptions : exception class=org.apache.cocoon.ResourceNotFoundException name=not-found/ exception class=org.apache.cocoon.components.flow.InvalidContinuationException name=invalid-continuation/ I noticed further down the errorhandling page you cite, there is mention of null pointer excpetions : A NullPointerException occurs, because something went completely wrong in the application: All handlers are not configured for such an exception and so the root sitemaps default handler will apply to it showing a general error page. Does this mean it is not possible to configure handlers for this type of exception and therefore not possible display a customer error page? The Background --- The reason for this query is that I am passing a query string parameter to a page which pulls in content from an xml file. For example www.mydomain.com/popup.html?id=11 : This displays a popup using content stored in a file called 11.xml. If the following is typed into the browser : www.mydomain.com/popup.html?id=foo there is no xml content to display because the is no foo.xml file and thus a NullPointerException is thrown. I would like a nice error page to be display in this instance.

Why are you letting an NPE through rather than checking for null and throwing a more descriptive exception type? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Pointer to good Java Binding Cocoon Forms docs?
I am at a point where I need good step by step instructions on binding a CForm to a Java object (in the JavaBean idiom). I'm talking from the beginning. The reference docs on the Cocoon site are "ok" if you have the environment set up already. I have done Google searches and tried following the samples, but I'm still hit and miss here. I'm staring up the end of a deadline and I only have some frustration to show for it. I believe I only need some coaching at this point, but there isn't anything that really qualifies for "This is where you begin and how things work together". I need some kind of pointer, please. I know CForms works, because of some of your comments. I just can't seem to get it working for me. -- Berin Loritsch Owner Work: 571-215-7708 Email: [EMAIL PROTECTED] IM: [EMAIL PROTECTED] (MSN) http://www.linkedin.com/in/bloritsch D-Haven 20044 Great Falls Forest Dr. Great Falls, VA 22066 USA See who we know in common Want a signature like this?
Re: Pointer to good Java Binding Cocoon Forms docs?
Hi Berin, In the sample there is a nice step by step tutorial of how bean framework works [1] lookup for Binding samples. Best Regards, Antonio Gallardo.

[1] http://cocoon.zones.apache.org/demos/21branch/samples/blocks/forms/ It's not a "how to" which is what I need. It's a working sample and I have to figure out by reverse engineering how the thing works. I need it, not only for myself but for my colleagues as well. This is the text I see: Cocoon Forms has a binding framework which assists in copying Java-bean or XML (DOM) data into a form and back. XML Binding - A form for just editing an XML file. Simple XML Binding - A form for just editing XML data. Illustrates the XMLAdapter. Bean Binding - A form for just editing a Java bean Step-by-step tutorial into individual binding features: 1. Binding Simple Values - fb:*/@direction and fb:value/* 2. Lenient Binding - fb:*/@lenient 3. Aggregate Binding - fb:aggregate 4. Heavy Form - Form with lots of select boxes - test memory utilization, performance 5. Custom Bindings using Java or _javascript_ - fb:_javascript_ and fb:custom 6. XML binding using namespaces - Using XML binding with complex namespaced XML And on each link is an example of a form. There's no link to a "how to" or tutorial there. -- Berin Loritsch Owner Work: 571-215-7708 Email: [EMAIL PROTECTED] IM: [EMAIL PROTECTED] (MSN) http://www.linkedin.com/in/bloritsch D-Haven 20044 Great Falls Forest Dr. Great Falls, VA 22066 USA See who we know in common Want a signature like this?
